Answer 1

I found the answer:

First in AppDelegate.m replace kEAGLColorFormatRGB565 with kEAGLColorFormatRGBA8, Second, as the following code, the last 4 lines is important:

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"]];
_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:_moviePlayer];

[_moviePlayer respondsToSelector:@selector(setFullscreen:animated:)];
_moviePlayer.controlStyle = MPMovieControlStyleNone;
_moviePlayer.shouldAutoplay = YES;
_moviePlayer.repeatMode = MPMovieRepeatModeOne;
_moviePlayer.view.frame = CGRectMake(0, 0, 300, 300);

UIView* glView = [CCDirector sharedDirector].openGLView; // attention
[glView.superview insertSubview:_moviePlayer.view atIndex:0]; // attention
glView.opaque = NO; // attention
glClearColor(0.0f, 0.0f, 0.0f, 0.0f); // attention
